Same here, tried the old hold select button while loading and that did not work, can see my account info just fine. Just now deleted and redownloaded the app it wanted to download and install version 2.14. Relogged in and it seems to be working fine now.

I did the delete->reinstall fix earlier today and it worked for a while, but now it's back to giving the PSN sign-in error again just like before. Getting sick of this stupid problem coming back every couple of weeks for the last 3 months or so, it's ridiculous.

For what its worth I do not believe this problem is a netflix issue as much as a psn issue. I noticed this problem first by trying to sign into nascar2011. that issue has persisted for a couple of weeks. It wasnt until to day that netflix became an issue. over the last couple of weeks netflix had no issues while the nascar game would not sign in and now, in one day netflix worked fine and two hours later when attempting to sign in again I now have the same issue as posted by anonomous above.
